Yesterday CFan shared with you the analysis of the expansion capability of USB-A interface with you (see "
Data type USB Type-Ch
Many mainstream price notes themselves The USB Type-C interface only supports data transmission. We can understand it as a different USB-A, which is the beggar in the Type-C interface family.
USB-A has disadvantages, such as if you want to expand HDMI, you need to integrate an independent display chip in the dock.
The good news is that the USB Type-C on the mobile phone is functionally compatible with the notebook, and USB is also available. Type-C is a future trend, so peripheral manufacturers prefer to launch docking products with USB Type-C interfaces, which are more diverse in types and quantities. The price is often cheaper than docking stations with USB-A interfaces when the types and quantities of interfaces are the same.
full-function USB Type-Ch
If the USB Type-C on your home notes is a "full-function" type, then congratulations, it not only supports data transmission, DP video output and USB PD protocol charging functions, but also supports more luxurious docking station devices.
Due to full-function USB Type-C natively supports PD, so the HDMI on the dock can be output to a maximum of 4K resolution, which can be connected to the monitor and multiple USB storage peripherals at the same time and will not consume additional CPU resources.
However, the more functions the USB Type-C docking station, the corresponding control chip is also required to integrate, so the price is not too cheap. It is just that when it is combined with the full-featured USB Type-C interface, it can play all the performance 100%, bringing a user experience comparable to the native interface.
full-featured docking station also needs to integrate PD charging chips, Hub chips and HDMI conversion chips. Whether
supports charging is an important criterion for measuring the grade of USB Type-C docking stations and is also the main factor that widens the price difference. Because many notebooks use USB Type-C is the only charging interface, and it cannot be charged when connecting docks without charging.
recommends that everyone choose USB Type-C docking station that supports charging and docks that support charging. The competition is whether it supports PD3.0 charging protocol. Some docks that support PD2.0, when unplugging (connecting to the dock) charging cable, the HDMI and USB devices connected to the will flash and reply, while docks that support PD3.0 will not be affected.
Many full-featured USB Type-C complies with USB 3.1 Gen2 or 3.2 Gen2 standards and have a 10Gbps transmission rate. However, USB The USB interfaces on the Type-C dock are mostly USB3.0 (5Gbps) standard. When reading a super-high-speed mobile solid-state drive, please directly connect to the USB Type-C on the note itself, and do not use the dock.
's most luxurious Thunderbolt 3
Thunderbolt 3 (it will be upgraded to Thunderbolt 4 in the future and will be included in the USB4 standard, and its transmission rate is still 40Gbps) function is USB The ultimate that Type-C interface can achieve, and you can enjoy emperor-level treatment.
In addition to supporting all the docks mentioned above, it can also connect to external graphics card boxes, allowing thin and light notebooks to use the RTX2080 dedicated to desktops to smoothly run the latest 3A game masterpieces. In addition, the docks that support Thunderbolt 3 can also lead to a dedicated Thunderbolt 3 interface, which can perfectly adapt to ultra-high-speed mobile solid-state drives and obtain a transmission speed of nearly 1000MB/s.
plays a variety of docks
good The design is also a competition for the difference between docks. The editor recommends two types of products to you. One is the equipped dock, which can "stand up" the dock to effectively reduce the use of desktop space.
And the other is the dock that can act as the docks, which can play the docks with the docks, which can throw some extension interface behind the notes themselves, and the space for placing the interface is more abundant.
In short, when purchasing docks, we need to consider it in combination with the equipment and future needs. For example, the USB of the laptop at home Type-C only supports data transmission. If you choose a dock with USB, DP charging and HDMI output interfaces, neither the latter two interfaces will be available.However, if you still have plans to replace a new laptop with a full-featured USB Type-C interface in the future, the dock you buy now can be reserved for new products, and it also eliminates secondary overhead.
